In recent years, 2D layered materials, including graphene, topological insulators, transition metal dichalcogenides, black phosphorus, MXenes, graphitic carbon nitride, and metal‐organic frameworks, have attracted considerable interest due to their potential applications in the fields of physics, chemistry, biology, and energy. Their rise in the field of nonlinear photonics began around 2009 and has become an important research direction. Here, the synthesis techniques, nonlinear optical properties, integration strategies, and device applications of layered materials are reviewed. In terms of nonlinear optical properties, the focus is on saturable absorption and Kerr nonlinearity. On this basis, their applications in various pulsed lasers, including fiber lasers, solid‐state lasers, waveguide lasers, and related nonlinear optical phenomenon, are summarized. In addition, novel optical devices using layered materials, such as optical modulators, optical polarizers, optical switchers, and even all‐optical device, are also involved. It is believed that the development of 2D layered materials in the field of photonics will continue to deepen, thus laying a good foundation for its practical application.

“…For 2D materials, Z-scan and two-arm methods are often employed to characterize the Kerr effect and saturable absorption. [127][128][129] A classical Z-scan equipment is depicted in Figure 3a, where the sample is prepared on a translation platform toward Z direction. A nano-, pico-, or femtosecond light pulse can be divided into a reference and probe pulse.…”

that satisfy the growing needs for compact, small foot-print, highly efficient and broadband photonic and optoelectronic devices. In other words, the development between SA technologies and lasers is almost isochronous. By 1983, several mode-locked fiber lasers with actively doped fiber amplifiers were demonstrated largely driven by improvements in low-loss optical fibers. However, mode-locking with a dye SA was unstable in Nd:fibers at the time. [5] The early 1990s saw the semiconductor SA mirror (SESAM) invention which was a milestone in the realization of stable passive mode-locked pulses [6,7] and stable Q-switching. However, SESAM progress was impeded by the narrow operation bandwidth, challenging fabrication process, slow relaxation time and most importantly a weak mid-infrared (mid-IR) response. By contrast, 2D nanomaterials can possess shorter relaxation times with a highly efficient broadband response covering even the mid-IR. The fabrication methods, nonlinear optical properties and applications in optics, biomedicine, and other fields of 2D materials are shown in Figure 1. 2D materials are now the spotlight of SA research applications because of these unique properties along with stable quantum confinement, higher mechanical stability, and an inherently small-footprint. [8][9][10] Graphene has been a breakthrough 2D NLO material for a wide range of topics such as broadband optical modulation, [11] optical frequency mixing, [12] ultrafast laser generation, [13][14][15][16][17][18][19][20] and surface plasmonic. [21] Nevertheless, the development of this material is still limited to some extent [22] due to its innate gapless band structure and the weak electronic on/off ratio. Topological insulators (TIs) reveal a large modulation depth. However, the fabrication of TIs is complicated because of their two elements composition. [23][24][25] Transition metal dichalcogenides (TMDs) are unusable in the mid-IR region because of their large bandgaps. [26] In Group-VA monoelemental materials, black phosphorus (BP) is famous for the characteristic layer number dependent bandgap. [27][28][29][30][31][32][33][34][35] However, monolayer or fewlayer BP lacks of chemical stability at ambient conditions. [36,37] In addition, another Group-VA material, semiconducting antimonene, is relatively stable under ambient environment with a wide bandgap. [38] Bulk antimonene has great potential to become a TI as well as quantum spin Hall phase producer when the number of layers is under 22, respectively. [39] On top of this, antimonene is very chemically stable. It has good thermal conductivity, [40] high mobility, [41] excellent thermoelectric figure of merit, [42] and good optical properties, [43][44][45][46] which 2D materials have received significant attention from the scientific community due to their unique structures and excellent physical properties. A lot of applications are explored based on graphene, topological insulators, and transition metal dichalcogenides. With further development of 2D materials, other Group-VA...
